Welcome to /dcsvg/ where we discuss security vulnerabilities caused by stagnant C/C++ which is preventable by default by modern languages and their compilers.
>ITT
Use-after-free vulnerability in fs/crypto/ in the Linux kernel before 4.10.7 allows local users to cause a denial of service (NULL pointer dereference) or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be freed prematurely.
>Exploit summary
This exploit would let an attacker invoke denial of service in Linux. Authentication is NOT required to exploit this vulnerability.
>Caused by
Use after free.
Here’s a simple example of user after free in C, it's a valid C code:uint8_t* pointer = (uint8_t*) malloc(SIZE);
...
if (err) {
abort = 1;
free(pointer);
}
...
if (abort) {
logError("operation aborted before commit", pointer);
}
>How modern languages tackle this issue:
Like C++, Rust uses the RAII approach everywhere (Resources Acquisition Is Initialization). That means that every variable is deterministically freed when it goes out of scope (= a pair of curly braces). So with “safe” Rust, you NEVER need to worry about freeing memory.
But Rust doesn’t stop there. It goes a crucial step further. It won’t let you access memory that was freed! That’s enforced via the Ownership rules.
In Rust, variables have a property that’s called Ownership.
An owner has the rights to use its data freely. Also, it can lend its data for a limited lifetime (= Borrowing).
Moreover, data can only have a single owner. Thus, the scope of the owner dictates where the data will be freed (via RAII).
TLDR:C == GUARANTEED SECURITY EXPLOITS
>Why does windows has less exploits in comparison
Written in C++, it has RAII

So, any of you guys use a RAID of some short?
I am thinking about setting one up, but I seem to find a lot of people complaining about RAID not being reliable enough for the cost, making most people be better off with manual mirroring in different drives.
Thoughts?

Decide what you want it for. RAID is supposed to provide redundancy first, and the speed aspect is an afterthought. It's there to make sure you don't lose access to the live copy of your data.
Level 1 is mirroring, and while it's possible for it to provide read speedups, I've never seen an implementation where it does. It's as fast as your slowest disk, and gives you the chance to replace one bad drive without losing data. Low CPU overhead for software RAID.
Level 5 and 6 stripe your data across multiple disks (minimum 3 for R5, 4 for R6). This gives you the chance of replacing one (R5) or two bad (R6) drives without losing data. There's a noticable write speed hit, and a substantial CPU load during rebuilds. Low CPU load on a modern processor though. Rebuild times can be really long if you're on 4tb disks. ZFS has its own similar thing called RAIDZ, but it really is the same idea under the hood.
Level 0 is striping, and offers no redundancy. It was literally an afterthought, and should only be used if you're STARVED for iops, and have good, continuous, backups.
I use all the forms mentioned here, both at work and personally. It's got problems, but it's also the only game in town for reliably storing that much data locally.
>>
>>60058286
Manually mirroring will still make into a raid type depending on the configuration as anon states above.
>>
>>60058475
Forgot to add. Lookup the Backblaze quarterly reliability report. Choose drives that are shown to be reliable by the numbers.
I got a deal on a certain model of 2TB WD greens a while back, and they're horrible. Literally in 5 years, out of 10 drives, 3 are left working. Had I read the report first, I wouldn't have bought them.

How long must we be kept waiting inside our flesh prisons? Inside our meat shells?
Each one of us a prisoner, unable to truly connect with any other. Our souls yearn to bond but they cannot.
We cannot truly progress in our current state. The human body is an evolutionary dead end.
How long until we are free?

how can i turn this:
A,a1,a2,a3
B,b1,b2
into this:
A,a1
A,a2
A,a3
B,b1
B,b2
using whatever tool works (bash/sed/python/excel...)
all the elements are strings (of variable length)

Following the rules of English, in the construction “Foobar Linux” the word “Foobar” modifies “Linux”.
This basically means “Foobar's version of Linux”, but a Foobar GNU/Linux system includes more than just a modified kernel.

I'm thinking of getting a new desktop because my laptop is shit and my iPhone runs faster than it. Initially I just want something that runs better than my shitty $300 Lenovo POS and also better than my phone so I can stop using my phone as a primary computer, but I also want to play video games on it. Initially I'd consider getting a gaming PC, but when I think of the games that I would play on it I start to think that I may not need a full gaming rig and a standard office computer might actually be all I will need for what I would do on it.
Any advice?

Figure out the system requirements for the games you'd want to play. Build a system based off of those requirements.
>>
>>60057732
Looking over the PC requirements for most of the games I want to play, the newest operating system for many of them is Vista since most of these games are quite old.
The newest ones are 2: Soma and the Bethesda RPG because Skyrim and New Vegas are pretty much the same.
Though there are a few other relatively new games I'm interested in, but those are also relatively simplistic like FTL or Stardew Valley. And while I do you know building a PC is usually the way to go, I'm thinking with the games I'm wanting to play I could just go down to Best Buy and buy a pre-built one

I know Java is objectively better for Android development, but for reasons I'd much prefer to use Ruby.
Is using Ruboto a stupid idea? I hear it's slow, but how slow are we talking?
I figure I can write/import Java libraries for the resource intensive parts.

Generally these projects that combine languages are shit. Jruby is painful, Cython is painful, etc, etc. The documentation is poor, you'll tear your hair out figuring out how to do stuff that's very well documented in the official environment.
And I say this as someone that fucking loves ruby.

It's a bad idea, plain and simple. You'll run into latency and memory issues. Use Java, Kotlin or something like React Naive.
